When your drone needs stable power without adding unnecessary weight, choosing the right battery configuration matters. The 18650 6s1p battery pack combines six 18650 cells in series to provide a nominal 22.2V output, while its 3000mAh capacity delivers 66.6Wh of energy. For drone builders and OEM buyers, the challenge is not simply finding a battery with the right voltage. You also need consistent cells, suitable connectors, reliable manufacturing, and a configuration that fits your application. Shenzhen Defond Technology Co., Ltd. develops drone battery solutions covering cells, BMS, and PACK manufacturing, helping you match battery specifications with actual operating requirements.
What Is an 18650 6S1P Battery Pack?
An 18650 6s1p battery pack uses six 18650 lithium-ion cells connected in series. The “6S” configuration increases voltage, while “1P” means the cells are not connected in parallel.
For this 18650-6S1P-22.2V-3000mAh model, the key specifications include:
- Nominal voltage: 22.2V
- Capacity: 3000mAh / 3Ah
- Energy: 66.6Wh
- Discharge rating: 10C
- Cell model: Sunpower 18650-30T
- Connector: XT60
- Weight: 311.5g
- Dimensions: 100 × 75 × 60mm
This configuration can be particularly useful when your drone system requires a 22.2V-class lithium-ion battery while keeping the pack relatively compact.
18650 6S1P Lithium Battery Specifications
The battery uses Sunpower 18650-30T cells and is designed around a 6S1P configuration. With six cells connected in series, the nominal voltage reaches 22.2V based on a typical 3.7V nominal voltage per lithium-ion cell.
The 66.6Wh energy capacity gives you a straightforward way to evaluate whether the pack suits your application. However, actual flight time depends on factors such as motor load, payload, flight conditions, ESC efficiency, and average current consumption.
18650 6S1P vs Other Battery Configurations
Understanding the configuration helps you avoid selecting a battery with the wrong voltage or physical requirements.
| Configuration | Cell Type | Typical Nominal Voltage* | Parallel Cells | Suitable Search Intent |
|---|---|---|---|---|
| 4S1P | 18650 | 14.8V | 1 | Lower-voltage drone systems |
| 6S1P | 18650 | 22.2V | 1 | 22.2V drone battery applications |
| 6S2P | 18650 | 22.2V | 2 | Higher-capacity applications |
| 6S3P | 21700 | 22.2V | 3 | Higher-capacity battery systems |
*Nominal voltage is based on approximately 3.7V per lithium-ion cell.
The important distinction is that increasing the number of series cells raises voltage, while adding parallel cells increases capacity and current capability. Therefore, a 6S2P or 6S3P pack should not be treated as a direct replacement for a 6S1P pack without checking your power system.
How to Choose an 18650 6S1P Li Ion Pack
Before you order an 18650 6s1p li ion pack, you should evaluate your complete electrical and mechanical requirements.
1. Confirm the Required Voltage
Check your drone’s power system and confirm that a 22.2V nominal battery is appropriate. Using an incompatible voltage can affect motors, ESCs, flight controllers, and other components.
2. Calculate Required Capacity
Estimate average current consumption and expected operating time. The 3000mAh capacity provides a defined starting point, but your real-world flight duration will depend on the complete drone system.
3. Check Discharge Requirements
This model is specified at 10C. You should compare the battery’s rated discharge capability with your drone’s continuous and peak current requirements rather than selecting a battery based only on capacity.
4. Verify Size, Weight, and Connector
The pack measures 100 × 75 × 60mm, weighs 311.5g, and uses an XT60 plug. Confirm the battery compartment, cable routing, connector compatibility, and overall aircraft weight before integration.
5. Discuss Custom Requirements
If the standard configuration does not match your drone, you can discuss cell selection, BMS requirements, PACK design, dimensions, connectors, and production quantities with Shenzhen Defond Technology Co., Ltd.
